Purpose: This study aimed to identify the relationship between the attitudes toward doping, sport orientation, and perceived motivational climate in sport, and to provide useful information on the anti-doping strategy. Methods: A total of 567 athletes in 21 sports completed four questionnaires Performance Enhancement Attitude Scale (PEAS), Sport Orientation Questionnaire (SOQ; competitiveness orientation, win orientation, goal orientation), Task and Ego Orientation in Sport Questionnaire (TEOSQ; task orientation, ego orientation), and Perceived Motivational Climate in Sport Questionnaire-2 (PMCSQ-2; ego-involving and task-involving climates). They were divided into four categories: speed/power (n=201), endurance (n=154), motor skill (n=119), and team (n=93). We identified the difference of variables among four categories and verified possible factors significantly associated with attitudes toward doping. Results: The PEAS of athletes in both speed/power sports and Team sports was higher than motor skill sports, and the team sports athletes also showed higher PEAS than endurance sports athletes. In speed/power sports, the task of TEOSQ and the win of SOQ were related to PEAS, and in endurance sports, the task of TEOSQ and the ego-involving of PMCSQ were related to PEAS. In motor skill sports and Team sports, the task-involving of PMCSQ and the goal of SOQ were associated with PEAS, respectively. Conclusion The results of this study provided new insights into the psychosocial mechanisms of attitudes toward doping, and it would contribute significantly to effective anti-doping strategies based on sports characteristics.
